In the mobile telecommunication systems the microcellular systems are needed to accommodate the increasing subscribers, especially in PCS environment. In that case the paging signaling cost minimization problems are arised. Recent researches introduce the location registration methods and cluster paging methods to minimize the paging signals. Cluster paging methods used the appropriate sized paging zones considering the existing probability of the subscriber of each cell. However this method can reduce the paging signal, the time delay of call setup becomes large. If we decide the small paging zone to reduce the paging signals, the call setup delay is larger than that of large paging zone. Thus, we cannot improve the call quality. In order to improve the call quality considering the minimization of the paging signals, we use the location registration methods. In this method, we divide the total area into small subareas and all subscribers are registered in that subarea. If a subscriber moves into another subarea, the location updating is occurred. In this research we analyze the paging and location updating signal functions to improve the paging and location registration method. The appropriate location area size is determined by the ratio of user velocity to call arrival rate and the ratio of location updating cost to paging cost. If we can construct the appropriate sized location areas to each subscriber according to the subscribers characteristics, we can minimize the location updating and paging signals. This method is called individual location registration scheme. However we cannot construct the own area to each subscriber, we use the multi-layered location area scheme. In this scheme we construct some layered location areas according to the pre-determined subscriber characteristics of the group and each subscriber belong to appropriate sized layer. We decide the pre-determined subscriber characteristics of the group and subscriber grouping according to t...
